When to Call a Professional
If you have tried every step above — including replacing the HDMI cable, testing all HDMI ports, updating the firmware, and performing a factory reset — and error code 8202 still appears on every HDMI port, the HDMI input board or main board inside your LG TV may be physically damaged. At this point, contact LG Support at 1-800-243-0000 or visit an authorized LG service center. Repair or board replacement requires opening the TV and handling internal components, which should only be done by a certified technician. If your TV is still under warranty, do not attempt to open the unit yourself as it will void the warranty.Frequently Asked Questions
What does LG TV error code 8202 mean?
Error code 8202 on an LG TV means the HDMI input signal being received is unstable or interrupted. This is most commonly caused by a loose or damaged HDMI cable, a faulty HDMI port, or a source device outputting an incompatible resolution or refresh rate.
Can a bad HDMI cable cause LG error code 8202?
Yes, a damaged, low-quality, or loosely connected HDMI cable is one of the most frequent causes of error 8202. Always try replacing the HDMI cable with a new high-speed HDMI cable as one of your first troubleshooting steps.
Why does my LG TV keep losing the HDMI signal?
Repeated HDMI signal loss on an LG TV is usually due to a failing cable, a damaged HDMI port, or an incompatible signal from the connected device. Try a different HDMI port, use a new cable, and lower the output resolution of your source device to see if that stabilizes the connection.
Does turning off HDMI Ultra HD Deep Color fix error 8202?
In many cases, yes. The HDMI Ultra HD Deep Color (Enhanced) setting requires a high-quality HDMI 2.0 or 2.1 cable and compatible source device. If your cable or device does not fully support this mode, disabling it in your LG TV settings can eliminate the signal instability causing error 8202.
Will a factory reset fix LG TV error code 8202?
A factory reset can fix error 8202 if it is caused by a software or firmware glitch within the TV. However, if the issue is caused by a physical problem such as a damaged HDMI port or broken cable, a factory reset will not help. Always try the cable and port steps first before resorting to a factory reset.
